A few basic tube questions

For starting info i just purchased a pair of Quicksilver mid mono amps . These are my first tube amps i have owned .

Questions are : I plan on buying several sets of tubes for these amps by different manufacturers. When i have found the ones that i feel i like the best how do i sell the others that will have had an hours worth of use ?

Second question is in regards to the varients my amp can use . They are el34 , kt88,kt90 , and maybe a few more .Will all manufacturers of an el34 sound similar . Or might one el34 sound like someone elses kt 90 .

Third question is in regards to my new dodd preamp . That uses one tube of the 6 volt ilk . There are one of those as well in the quicksilver amps . Is it a good idea to use the same in the pre and amp ?

Lastly if anyone is interested in giving a quick (general description) on the differences of the el34 ,kt88 ,kt90 tubes .

Jmcgrogan2... You bring up a good point; Who wants to buy some unknown used tubes?
I have no tester, so in my ads I did mention the dealer's name and the reason I was selling which was always "auditioned the tubes in my gear" and I will give the hours used...200 to 300 for auditioning. I will also draw attention to my positive feedback.
I have had sold a few sets of very expensive NOS tubes for about half price; I'm talking about $200+ tubes. There was a high demand for these tubes and I believe that is why they sold.

I am planning on using either Tubemonger or The tubestore . Or any of the top hits from a google search . Do i need to be leary of not getting what i am paying for or as these websites describe the tubes ? New condition is what i was planning . Is it wise to buy the small tubes that last alot longer used ?

In my experience, I find a broader choice of high quality NOS (new old stock) from the likes of Vintage Tube Services, Brent Jesse, Upscale, etc.

I've found NOS tubes gerally sound better, and should last longer, but they are more expensive. Try a few, and see.

Best regards,
Dan

You're making it way too complicated and doing it too much too quickly. The responses to your question are good, but they are encouraging your over complication. You are new to tubes and you've just secured two new tubed components. Spend the next 4 to 6 months enjoying what you have and acclimating yourself to their sound. It's a cliche, but rediscover your music collection. Once you get over the newness of the sound you'll be in better position to judge what you want to change, if anything.

BTW, what loudspeaker are you using with the Quicksilvers?

I am running a pair of King Sound King electrostats. I was told by Gary Dodd whose preamp i bought that he just throws in a cheap russian tube because he expects owners will choose their own tube . I do not want to listen to that tube for very long.
